Original commit message from CVS: * gst-libs/gst/interfaces/mixertrack.c: (gst_mixer_track_class_init), (gst_mixer_track_get_property), (gst_mixer_track_set_property): API: add "untranslated-label" property which should be set by implementations at construct time (#414645). * ext/alsa/gstalsamixeroptions.c: (gst_alsa_mixer_options_new): * ext/alsa/gstalsamixertrack.c: (gst_alsa_mixer_track_new): Set "untranslated-label" when constructing mixer track objects. * tests/check/elements/alsa.c: (GST_START_TEST), (alsa_suite): Unit test to check the above.
